Groundwater flows and energy consumed for groundwater extraction<br />
Energy consumption has been extrapolated from the following assumptions:<br />
- Average groundwater table depth in <strong>Zaragoza</strong> = 5m<br />
(Personal communication, Local agenda 21 Office)<br />
- Average energy consumption for groundwater extraction<br />
= 0.02 Kwh/m3 at 5m height<br />
